Abstract
Improvements in Modeling Water Resources in West Virginia
Track: Water Resources
Author(s): Jacquelyn Strager
The National Hydrography Dataset (NHD) is the nationwide standard for surface water mapping. In West Virginia, the NHD has been completed at the 1:24,000 map scale. The WV Statewide Addressing and Mapping Board (SAMB) has also mapped hydrology at a local 1:4800 map scale, and has produced a statewide 3m DEM. The local streams dataset and the 3m DEM have implications for future hydrologic mapping and modeling. Local scale streams offer more current stream geometry and increased spatial resolution. However, the local scale stream geometry raises several questions on the benefits and costs of increased data resolution. The completion of the 3m DEM also offers an opportunity to refine existing hydrologic modeling datasets for WV. A case study on the value of the improved resolution datasets will be presented, as well as an analysis of stream changes over time in an increasingly altered landscape.
